The journal Applied Surface Science (okay, so maybe it’s not called ASS at the home office) is retracting a pair of articles in its December issue.
The first, “Structure and mechanical properties of Ni–P electrodeposited coatings,” appeared in 2009 and was written by a group of researchers in Beijing. It has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Its problem: Plagiarism. According to the retraction notice: Read the rest of this entry »
Last week, we reported on a retraction in the Journal of Analytical Atomic Spectrometry that left us a bit puzzled. The notice referred to a problem with “the way the data was presented,” but the authors told us this was just an error picked up in proofreading, somehow after the paper had been published online.
We now have much more of the story. The Royal Society of Chemistry’s May Copsey, who edits the journal, tells Retraction Watch: Read the rest of this entry »
The Journal of the American Chemical Society has retracted a 2009 paper on ethylene polymerization after the authors said they were unable to replicate their findings.
The article, “Bimetallic Effects for Enhanced Polar Comonomer Enchainment Selectivity in Catalytic Ethylene Polymerization,”came from the lab of Tobin Marks, a highly decorated — and grant-and-royalty-generating — chemist at Northwestern University.

The article, “Granular and intergranular conduction in La1.32Sr1.68Mn2O7 layered manganite system,” came mostly from a team of physicists at University Ibn Zohr, and appeared in June.
The clincher: According to the journal, the researchers did not possess the proper lab equipment to perform the study as reported.
The article, “Detoxification of high-strength liquid pollutants in an ozone bubble column reactor: Gas–liquid flow patterns, interphase mass transfer and chemical depuration,” appeared in August 2011 and was written by Rodrigo J. G. Lopes and Rosa M. Quinta-Ferreira, from the Group on Environmental, Reaction and Separation Engineering in the Department of Chemical Engineering at the University of Coimbra. The paper has been cited twice, according to Thomson Scientific’s Web of Knowledge, both times by the original authors.
Here’s what the abstract has to say about the work: Read the rest of this entry »
The Journal of Saudi Chemical Society has retracted a 2011 paper by a researcher who lifted the entire article from a previously published paper by someone else.
The paper in question, “Synthesis and antimicrobial activity of some new quinazolin-4(3H)-one derivatives,” came from Adnan Kadi at Kind Saud University in Riyadh. But according to the retraction notice, only a few words in that title — “some” and “quinazolin” were accurate. “New,” certainly not. (We suppose “derivatives” hits the mark, but for the wrong reason.) Read the rest of this entry »
